Swing Training Device

ABSTRACT

A swing training system which includes a light-reactive surface, and a training device having a light source capable of striking the light-reactive surface and creating a temporary visual representation of the path of the light over the surface. The device can include multiple light sources, which according to the arrangement of the illuminated paths on the surface indicate if the proper alignment was achieved during a swing. In accordance with at least one embodiment, an individual can use the swing training system to perform a stroke to simulate striking a golf ball on the surface. The movement path of the device over the pad is visually illustrated by the reaction of the light source with the light-reactive material such that the individual can observe the actual stroke direction and alignment indicated by the light source path. The visual representation of the actual path fades in a short amount of time such that the individual can perform subsequent strokes in order to improve the correspondence between the actual stroke and the optimal stroke.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. patent application Ser. No. 14/073,801 titled Swing Training Device and filed on Nov. 6, 2013, which is hereby incorporated by reference in its entirety herein.

FIELD OF THE INVENTION

The present invention generally relates to swing training devices, and more specifically, to a swing training device that utilizes at least one light beam to provide immediate feedback to the user.

BACKGROUND OF THE INVENTION

A variety of different practice methods and devices have been developed in order to improve one's golf swing. These methods and devices focus on various physiological aspects of the golf swing, including body position, body alignment, swing path, and follow-through. However, the presently available devices are limiting in their ability to provide comprehensive feedback on a complete and realistic swing.

Of the methods and devices presently available, the majority of them focus on the body alignment of the user in an attempt to help the user strike the ball in a desired direction. While presently available methods and devices provide feedback on the user's body alignment by analyzing swing path, they often require the user to lift or turn his or her head during the stroke in order to receive the feedback. This can interfere with the user's body alignment during the stroke.

One of the most widely regarded teaching lessons in the game of golf is to teach a golfer to swing within a single plane starting with their backswing, forward swing and follow through. This teaching lesson has been widely regarded for decades as the most ideal golf swing, which has been taught by golf professionals for years. One of the most highly respected and decorated golfers of all time, Mr. Ben Hogan, taught this in his classic book, Ben Hogan's Five Lessons (1957), the need for golfers to swing within a plane, but “being consciously attentive to [the plane] does not help . . . ”. A slightly modified methodology teaches a pupil to swing within a plane, wherein the backswing is one plane and the forward swing with follow through is within a second plane.

Therefore, it is desirable to develop a method or device that provides feedback to the user in a manner that allows the user to keep his or her head still during the stroke and swing within a plane, one of the most highly regarded ideal swing characteristics. Also, the device should provide feedback for the entire motion of a stroke. Lastly, the device should be easy to use, durable, and easily stored.

SUMMARY OF THE INVENTION

In accordance with at least one embodiment of the present invention, a swing training system having a surface formed of a photoreactive indicating material and a swing training device is provided. The swing training device includes an indicator adapted for movement over the surface, wherein the swing training device is capable of interacting with the photoreactive surface to form a visual representation of a swing path of the swing training device, and a swing analysis device operatively coupled to the swing training device and having a 3-D accelerometer and 3-D gyroscope capable of measuring the linear acceleration and angular velocity of a swing training device.

In accordance with at least one embodiment of the present invention a golf swing training device is provided with a handle operatively connected to an indicator through a shaft, the indicator having, a UV light source capable of interacting with a photoreactive surface adapted to provide an indication of movement by the device, and an audio recording device for recording a short audio sequence.

DETAILED DESCRIPTION OF THE INVENTION

The various features and advantageous details of the subject matter disclosed herein are explained more fully with reference to the non-limiting embodiment described in detail in the following description.

Referring to FIG. 1, a swing training device is illustrated generally at 99. The device 99 includes a battery cage 100, a handle 102, a shaft 104, swing weights 106, and indicator 107. The indicator 107 includes a USB port 108, power switch 110, first and second light source 115, 119, and third light source 116. An exploded cross sectional view of the battery cage 100 is more specifically shown in FIG. 6. The handle 102 is operatively connected to the shaft 104. The handle 102 can be selected from a group of grip styles including a golf club grip of various shapes and constructions available on the market, a tennis handle grip, a hockey stick grip, baseball bat grip, or any other grip operatively attached to a device suitable for swinging, including alternative sporting devices. The shaft 104 can be constructed of any suitable material designed to operatively connect the handle 102 to the indicator 107. The shaft 104 can be ⅝ inch copper tubing, graphite, titanium, steel, aluminium, any selected golf club shaft, or alternatively may be a telescoping such that the length of the device 99 can be extended to suit a particular users' preference. When turned on by the on/off power switch 110 is capable of directing light sources 115, 119 such that when passing over a photoreactive surface 48 (See FIG. 8) a visual representation of the path of the swing of the device is formed.

The distance between the first light source 115 and the second light source 119 is approximately 1¼ inches, with the third light source 116 centered between them. Alternatively, the distance between the light sources 115, 119 may be between 1-2 inches. Alternatively, the distance between the light sources 115, 119 may be between ½ and 1 inch apart. In yet another alternative embodiment the distances between the light sources is less than ½ inch or greate than 2 inches. Alternatively, the device 99 can be constructed (not shown) in such a manner as to allow the user to modify the distance between the light sources 115, 119 while allowing them to continue to be directed on a parallel path to the axis of the shaft 104. Alternatively, the weights 106 may be removable to suit the particular users swing weight.

The first and second light sources 115, 119 include a focusing lens 114,118 and diode 117, 121. The light sources 115, 119 can be selected from a variety of suitable commercially available light sources. By example, the light sources 115, 119 can be a 405 nm, 5 mw UV laser. Alternatively, the light sources can be a 650 nm, 200 nm UV laser. In yet another alternative embodiment the light source 115, 119 can be less than 405 nm and less than 5 mw, or greater than 405 nm and greater than 5 mw. Such suitable light sources include those UV laser diodes commercially available from manufacturers such as Thorlabs (www.thorlabs.com) and Roithner Laser Technik (www.roithner-laser.com. Additionally, the light source 115,119 can be selected in combination with the particular photoreactive material utilized with the surface 48 to maximize the photoreactive qualities suitable for the purpose of a swing training device using known in the art reactive characteristics. Alternatively, the surface 48 may be constructed from florescence, phosphorescence, or alternative light reactive material, such that as a light source interacts with it, the surface 48 will provide a temporary indication to the user of the device 99. The reactive surface 48 may alternatively be a painted surface. The surface 48 may include a photo reactive surface when combined with a light source visually indicates the path of a swing from about ½ second to 3 seconds, or preferably about 1, 2 or 3 seconds. Alternatively, the surface 48 can present a temporary visual indicator of the swing path for greater than 3 seconds.

The third light source 116 is a laser that is directed upon the center axis of the shaft 104 and includes a laser module 112. The third light source 116 may be a red laser having a single focused light beam or be presented in the form of a ‘crosshair’ shape. The third light source 116 can be selected from a variety of commercially available laser diodes and is generally suitable for directing an indicating light up at least up to about 1 foot beyond the indicator 107.

In utilizing the training wand 32 to perform a stroke, an individual grasps the handle 36 and moves the training wand 32 in a generally pendulum-like fashion to simulate a golf stroke within a plane. The golf stroke may include one or more planes, such as a slightly different plane for the backswing as for the downswing.

FIG. 2 represents a cross sectional view of the device 99 shown in FIG. 1 along lines 2-2. The indicator 107 is expanded and represented in FIG. 3, while the end of the device 99 having the battery cage 124 is expanded in FIG. 6. A centrifugal power switch 125, also referred to as a centrifugal power mechanism 125, is provided for activating the first and second light sources 115, 119. The power switch 125 includes a plurality of ball bearings 120 enclosed within a case 144 and an activation switch 128. As the device 99 is rotated or swung generally around an axis proximal to the first end 101 the indicator end 103 accelerates, causing the bearings 120 to press upon the switch 128, thereby activating the first and second light sources 115,119.

Referring to FIGS. 3-5, the USB, or alternatively mini-USB port, 108 is provided as a means for charging and/or data transfer. The laser module 112 is present, which can be selected from a range of commercially available light sources. The module 112 is capable of producing a light stream, cross-hair, or alternative configuration of light indicia for the user to align the device 99 for purposes of practicing a swing. The printed circuit board 126 is also identified for enabling proper function of the device 99, including the transfer of power to the light sources during the swinging motion and otherwise. An outer structural piece 142, side piece 148, cover 150, and end piece 144 of the indicator 103 form a portion of the outer structure of the head 103 of the device 99. Bolts 130, 132 are used to secure the various pieces of the head 103.

Referring to FIG. 6, a battery cage 100 is provided with a power means 140. A laser diode 134 and battery contacts 136, 138 are provided. The power means 140 can be a replaceable battery, rechargeable battery, or alternative means for storing and providing power to operate the device 99. The laser diode 134 enables the user to identify their swing path during the backswing of a golf swing. As the swing extends backwards the light generated by the diode 134 will become visible on the surface 48.

Preferably, to train an individual utilizing the training wand 32 or device 99 to swing in a manner consistent with striking a golf ball in a correct and consistent manner, notably within a plane, the training wand 32 is utilized in conjunction with an indicating surface 48.

The indicating surface 48 can be any desired shape or size, but representatively may be a generally rectangular shaped pad 42, for example, with a width of one foot and length of four feet although other dimensions may be employed as desired. In alternative embodiments, the indicating surface may be applied or painted directly onto a floor or wall. Alternatively, the surface 48 can be symmetrical, thereby allowing for left and right-handed golfers. In one embodiment, the pad 42, which carries the indicating surface 48, may be formed with an upper member 44 and a lower member 46 joined to one another by any suitable bonding or securing means such as an adhesive (not shown). However, the pad 42 can also be formed solely from the upper member 44, or can have the upper member 44 material applied to both sides of the pad 42. The lower member 46 is formed of a flexible, and preferably, high-friction material such as a foamed thermoplastic that can be positioned on a flat surface on which the training aid 30 is to be utilized. The thickness of the lower member 46 can vary as desired but may be, for example, between 1/32 and ¼ inches. The surface 48 may be constructed from any material known, whether commercially available, that is reactive to a light source. Alternatively, the device 32 may be used in conjunction with a surface that is not reactive to light. Alternatively, the device 32 may have a plurality of light sources with varying intensities and wavelengths ranging from 200-400 nm. In yet another alternative embodiment, the device 32 may have a plurality of light sources with less than 200 nm and greater than 400 nm wavelengths and intensities. In yet another alternative embodiment, a first light source 115 may be pulsing while a second light source 119 may be continuous to give the user a further indicator as to they nature of their swing. Alternatively, both light sources 115, 119 may be pulsing at the same rate or at different rates. Alternatively, there may be more than two light sources that are reactive with the surface 48.

The upper member 44 includes or may be formed of an indicating material forming the indicating surface 48, which is capable of visually illustrating the path the training wand head 38 or handle 36 takes when the training wand 32 is utilized to simulate striking a golf ball. In one embodiment, the indicating material forming indicating surface 48 is a phosphorescent or photoluminescent material that, when contacted by a light source, is energized when exposed to the light source, emanating from the training wand head 38 or handle 36, and presents a visual representation 50, as seen in FIGS. 11-14, of the path of the training wand head 38 or handle 36 over the material 48.

The upper member 44 may also include indicia 52 printed or otherwise applied to the indicating surface 48 of the upper member 44, so as to be visible from above. The indicia 52 may be in the form of an image of a golf ball in the center of the upper member 44, and stroke guidelines showing the “ideal path”. Instructions of use may also be printed in a discrete location, such as a corner of the pad 42. Indicia 52 can also have other markings optionally included, such as a lines (not shown) illustrating how far to move the head 38 from the initial setup position when swinging from certain distances, or other types of indicators.

Referring to FIG. 7, the indicator 38 of the training wand 32 contains a plurality of light sources, which may be in the form of one or more indicators 54 and/or red laser diodes 56, a power switch 58, a circuit board (not shown), a centrifugal switch 60, and wiring (not shown). The one or more indicators 54 on the training wand 32 can be any type of indicator capable of interacting with or energizing the indicating material 48 of the pad 42 in order to provide a visual representation of the path of the device head 38 or handle 36 over the pad 42.

Referring to FIGS. 7 and 8, and referring first to FIG. 7, in one embodiment, the one or more indicators 54 may take the form of a light source which emits a beam of light 62, 64 that upon striking the indicating surface 48, as seen in FIG. 3, causes the material of indicating surface 48 to react and form a visual representation of the path of the device head 38 thereon. The light source can be any suitable light source, such as an ultraviolet (UV) laser, for reacting with the indicating surface 48. The first and second light sources 115, 119 can be alternative light sources that react with a surface 48 to provide a temporary visual indication of a swing path.

Referring to FIGS. 9-11, in one embodiment, a red laser diode 56 in the head 38 is always ON when the device is powered ON by the power switch 58, and emits a red laser beam 66. This allows the user to align himself or herself and the device before practicing a swing.

Referring to FIGS. 12-15, the handle 36 of the training wand 32 also contains an indicator 54, which in one embodiment is a UV laser. In this embodiment, unlike the indicators 54 in the head 38 of the training wand 32, the indicator 54 in the handle 36 is always ON when the device is powered ON by the power switch 58, and emits a light beam 68 from the handle 36. This allows the user to receive a visual representation of their back swing, down swing, and follow-through.

Referring to FIG. 16, the indicators 54 in the head 38 are UV lasers and are only ON when the centrifugal switch 60 is turned ON from the swinging motion of the training wand 32. In another embodiment, the indicators 54 in the head 38 of the device are controlled by an accelerometer. This allows the user to receive a visual representation of their swing during contact with the ball.

Having described the construction of the training wand 32, the use of the training wand 32 will now be discussed. When using the swing training device 30, the pad 42 is positioned on a relatively flat surface, such as a floor, with the indicating surface 48 placed in an upwardly facing position. The training wand 32 is held by the individual such that the indicators 54 located in the training wand head 38 are perpendicular to and facing the pad 42. When it is desired to operate the training wand 32, the power switch 58 is activated. The individual can then line up the training wand head 38 accordingly with the indicia lines 52, in a proper position and proceed to take a stroke whereby the training wand head 38 is moved rearwardly and forwardly in a plane, as seen in FIGS. 8-9. The plane may be different dependent upon the particular user, and the device 99 need not be altered for users of all shapes and heights to utilize it for purposes of proper swing training.

Referring to FIGS. 9-11, at the beginning of the stroke, the red laser 66 is activated and used to align the stroke properly. Also at the outset of the stroke, the UV light 68 of the handle 36 is activated to provide feedback on the back swing and down swing of the stroke. As seen in FIG. 11, during the back swing and down swing, the head UV lights 62 are then activated by the centrifugal switch 60 or accelerometer. The training wand head 38 moves across the pad 42 and the light beams 62 from the indicators 54 strike and energize the indicating material 48, causing the indicating surface 48 to “glow”. Finally, the UV light 68 of the handle 36, provides feedback on the follow-through of the stroke.

After the completion of the stroke, the indicating surface 48 provides a temporary visual representation 50 of the path of the training wand head 38 or handle 36 over the pad 42, thereby showing the user the path of their actual stroke. This representation of the path can then be compared with the indicia 52 on the indicating surface 48 illustrating the “ideal stroke” path, such that the user can determine how close the actual stroke was to the “ideal stroke,” as seen in FIGS. 12-14.

Referring to FIGS. 17-19, and referring first to FIG. 17, the indicating surface 48 shows the temporary visual representation 50 in line with the indicia 52, indicating a proper swing. When the back swing is performed properly, the indicator 54 from the handle 36 of the training wand 32 will make a line in the same spot as the line from the indicators 54 on the head 38 of the training wand, thus making all three lines appear as one. FIGS. 18 and 19 show the temporary visual representation 50 out of alignment with the indicia 52, indicating that the actual path of the swing varied from the desired path represented by indicia. If the head 38 is rotated, the two indicators 54 in the head 38 of the training wand 32 will make two lines. Or, if the back swing is performed improperly, the indicator 54 from the handle 36 will not line up with the indicators 54 on the head 38. In order to distinguish the three lines left on the indicating surface 48 from the three different UV lasers, each UV laser emits a different pattern or shape of beam such as shown at 62, 64, 68.

With respect to the particular type of light utilized with the light source, the particular form of the material of indicating surface 48 will dictate the type or wavelength of light that can be used. More specifically, the frequency of the light beam 62, 64, 68 emitted from the light source must be higher than the frequency of light required to energize or charge the phosphorescent or luminescent material contained within the material of indicating surface 48. In one embodiment, the light emits a beam 62 with a wavelength of less than about 500 nanometers. The red laser diode 56 emits a different, non-activating, beam 66 with a wavelength of approximately 600-700 nanometers, which is used to align the device before the swinging action of the training wand 32.

After the user has compared the actual path to the “ideal path,” the visual representation 50 on the indicating surface 48 fades as the material becomes de-energized, thus allowing the indicating surface 48 to form a subsequent visual representation 50 during a subsequent stroke. The user can thus practice the strokes repeatedly to create the desired muscle memory for use during an actual golf game.

The training device 30 can be utilized in this manner for a large number of strokes because the pad 42, and specifically the material of indicating surface 48, can be successively de-energized and re-energized by the light beams 62, 64, 68 almost indefinitely. Furthermore, in order to maximize the visual representation 50 of the actual stroke on the pad 42, the training device 30 should be utilized in a low light condition where the indicia 52 is still easily viewable on the pad 42, but such that the visual representation 50 created by the indicator 54 moving over the pad 42 is easily viewable in contrast to the indicia 52.

The present invention contemplates any embodiment in which an indicator 54 is capable of interacting with the indicating surface 48 in a manner that temporarily represents the path of the training wand 32 over the indicating material 48. Also, a small amount of contact between the training wand 32 and indicating surface 48, which does not impede the stroke, is also contemplated. For example, the material of indicating surface 48 could be heat-sensitive material that locally changes color when contacted by a heat source, and the indicator 54 could be formed as a small heat source and moved over the heat-sensitive indicating surface 48. Further, the indicator 54 could be formed of a dry erase marker (not shown) or similar writing implement. When the training wand 32 is moved over the indicating material, it causes the indicator 54 to scribe a line (not shown) representative of the training wand head 38 path on the indicating surface 48.

Referring to FIG. 20, weights 80 made of an appropriate material and fastening means can be added to or removed from the club shaft 34 when the shaft is not attached to the handle 36 to achieve the proper swing weight depending on what club weight feels realistic to the user.

The exterior of the club head 38 can be covered with any suitable shock-absorbing material which allows for protection of the head and its contents. The shock absorbing material also acts as a safety feature if it unintentionally strikes an object.

Referring to FIG. 21, the shaft 34 of the club is detachable from the handle 36, and can be made out of aluminum or any other suitable material to be light weight while still maintaining strength. The shaft 34 may have an optional additional piece added or removed to adjust the overall length of the training wand 32.

Referring to FIG. 21, the handle 36 or shaft 34 encloses a suitable power source 70 such as a replaceable battery or a kinetic motor. The handle 36 is made to resemble a golf club grip, and is made of a rubber or similar material.

Referring to FIGS. 22-24, the centrifugal switch 60 activates when the user swings the training wand 32 in a direction shown at 72, thereby causing the force of small weights 74 to press down on an internal switch 76. Movement of the training wand 32 in the opposite direction, or cessation of movement of the direction 72, causes the weights 74 to disengage the internal switch 76 and therefore deactivate the indicators 54.

Alternatively, the shape of the training wand head 38 can vary greatly depending upon the particular construction of the device. In yet another alternative embodiment, it is contemplated that the indicator 107 can be attached to the head of a standard golf club and function in the same manner. The indicator 107 can be attached through a varied of known attachment means, including straps, bolds, ties, etc. In yet another alternative embodiment, it is contemplated that the indicator 107 is formed in the shape of a golf club head, including an iron, hybrid, wood, or other suitable golf club head. In such an embodiment, the device is a regular length golf club, having similar look, feel, and weight, in which the light sources are integrated within the club head and allows the device to function as the device 99 provided herein.

While the invention is well suited for use in practicing a golf swing, it is also contemplated that the invention may be used to trace the movement of any type of swing, and is not limited to a golf swing. In addition, it is also understood that the present invention may be used with or without the reference indicia on the pad.

A method for practicing a golf swing using a golf swing training device is contemplated. A user positions a photoreactive indicating material on a surface. The photo reactive material can be a thin coating such as layer of photoreactive paint applied directly to a flooring surface. Alternatively, the photoreactive material is a layer of a mat layed upon a flooring surface. The user positions themselves in close proximity to the indicating material while grasping a golf swing training device 99.

The golf swing training device is activated by the user, wherein the golf swing training device includes a plurality of light sources. Additionally, at least two of the plurality of light sources are capable of interacting with the photoreactive indicating material. The user swings the golf swing training device such that at least two of the plurality of light sources pass over the indicating material, wherein the indicating material and at least two of the plurality of light sources interact with each other to provide a visual representation of the path of the swing device as the swing device is moved over the indicating material. The positioning of the UV light sources through the swinging motion will provide an indication as to whether the user is swinging on the ideal swing plane. Slight rotation or deviation from the swing plane will represent an improper swing.

The user visually inspects of the path of the swing training device with indicia disposed on the indicating material surface, wherein the indicia represent a desired path of movement of the swing device. The indicia may include outlines of an iron or wood, depending upon size, as well as a central indicating line for focused swing training. The user can also swing the swing device with a modified swing path based at least in part upon the visual representation of the first swing.

In accordance with at least one embodiment of the present invention a swing training system which includes a light-reactive surface, and a training device having a light source capable of striking the light-reactive surface and creating a temporary visual representation of the path of the light over the surface. The device can include multiple light sources, which according to the arrangement of the illuminated paths on the surface indicate if the proper alignment was achieved during a swing. In accordance with at least one embodiment, an individual can use the swing training system to perform a stroke to simulate striking a golf ball on the surface. The movement path of the device over the pad is visually illustrated by the reaction of the light source with the light-reactive material such that the individual can observe the actual stroke direction and alignment indicated by the light source path. The visual representation of the actual path fades in a short amount of time such that the individual can perform subsequent strokes in order to improve the correspondence between the actual stroke and the optimal stroke.

In an alternative embodiment, the swing training device includes an alignment pad that is positioned on a flat surface. A golf ball can be optionally positioned on the pad. The pad includes at least an upper surface that is formed of an indicating material, the indicating material has a multitude of guiding indicia for comparative analysis to provide an indication to the user whether they are swinging outside a plane, whether they are following through with an open or closed club face, and whether they are swinging squarely through the impact zone of the ball. The mat may be symmetrical in order to allow for both left and right handed golfers to utilize the tool.

In at least one embodiment of the present invention, the training device also includes an indicator, which may be a training wand having a handle and a head region. The training wand may be the same size or shorter than a standard golf club. The training wand interacts with the indicating material of the pad in order to provide a visual representation of the actual path of the indicator during a stroke. This enables the user to compare the actual to an “ideal path”.

In at least one embodiment of the present invention, multiple lasers are used in order for the user to receive feedback on multiple aspects of their stroke. In one embodiment, the head region has a laser, which may be a red laser, which does not activate the indicating surface, and allows the user to adjust the device during the takeaway without leaving any marks on the indicating surface. The head region also has two UV lasers on either side to allow the user to visualize whether the head region was aligned properly during contact of the ball. The UV lasers activate the indicating surface to provide a visual representation of the swing path as the head region moves over the indicating surface. Finally, the handle has a UV laser that allows the user to visualize the back swing, down swing, and follow-through of the stroke. The UV laser activates the indicating surface to provide a visual representation of the handle position as the end of the handle points toward the indicating surface.

In at least one embodiment of the present invention, the use of UV lasers allows the user to have a more precise visual representation than if LED lights were used because they provide a more focused beam of light hitting the indicating surface. The visual representation of the actual path created on the indicating material remains visible for a sufficient amount of time to allow the user to compare their actual stroke with the “ideal stroke”. However, the visual representation on the indicating surface fades relatively quickly so that the indicating surface can be reused for subsequent golf strokes.

In another alternative embodiment, the swing training system includes a recording means (not shown) for recording the swing paths of the user using the device 99. The recording means may record the reactive paths of the light sources and provide swing analysis measurements, including speed, and analysis of the incorrect and correct swing paths.

According to another aspect of the present invention, the indicating surface is on an alignment pad, which is formed of a flexible material so that it can be rolled, folded, or otherwise collapsed for storage. The pad may also include a lower surface formed of a material different from the upper surface in order to provide a sturdier support. The pad may also be a thin coating on top of another permanent surface, such as a wall or floor.

Alternatively, the indicating surface is an artificial turf or simulated grass similar to those utilized at driving ranges and other golf practice facilities. The artificial turf material is coated with a light reactive paint or similar treatment such that each artificial grass blade, fiber, or matrix element is coated or treated with the light reactive paint. Exemplary practice mats are commercially available from many sources, including the following websites: http://duraprogolfmats.com, http://www.truestrike.com, http://www.allturfmats.com. A golf training system utilizing such mats may be particularly suited for the swing training device as described herein having a full length golf club and golf club head with either the UV light sources emitted from the bottom of the club head or in a device (see next paragraph) that clamps onto the shaft of a golf club.

In an alternative embodiment, the swing training device is a device containing the elements of the training wand head 38 of FIGS. 7 and 8 in addition to a clamping mechanism (not shown) particularly suited for attaching to a golf club shaft. Clamping mechanisms are known in the art, an exemplary golf club clamping structure can be found in U.S. Pat. No. 8,696,482, the entirety of which is hereby incorporated by reference. Alternatively, the device combining the wand head 38 and clamping mechanism is configured such that two UV lights are positioned equidistant from the shaft of a golf club and parallel to the axis formed by the shaft of a golf club. An alternative structure of the wand 38 enables the UV lights positioned on either side of a golf club shaft, such that the UV lights are directed on a parallel path to the axis formed by the center of the golf club shaft, wherein a line can be drawn through the axis formed by the shaft of a golf club and two axis' formed by the UV light paths.

In an alternative embodiment, a swing training system includes the combination of: 1) a surface formed of a photoreactive indicating material and a swing training device comprising an indicator operatively connected to a handle of the device or to a device such as a golf club, the indicator adapted for movement over the surface, and 2) a swing analysis device connected to a swing training device or a golf club, having a 3-axis accelerometer and a 3-axis gyroscope, such that linear acceleration and angular velocity of a swing training device or golf club is measured. An exemplary swing analysis device is described in U.S. Pat. No. 8,696,482, which is incorporated by reference, including all the patents and applications cited within U.S. Pat. No. 8,696,482, which are incorporated herein by reference. The swing analysis device is operatively coupled to the swing training device or swing device (i.e. golf club, tennis racket, baseball bat, other swinging device) through a clamp or other attachment means. Alternatively, a video recording device can be used in combination with #1 and #2. The combination of #1 and #2 enables a real-time visualization of a swing path as well as a 3-D visualization and graphic representation of a swing path. Such an alternative embodiment can include a “comment button”, enabling the user to press a button and configured to record a short audio message identifying information about the swing for later analysis. This comment button is an audio recording device, which can be a single button device operatively coupled to the swing training device, such that when the button is pressed the device records audio for a predetermined period of time. The predetermined period of time can be from 1 second to 60 seconds, and alternatively greater than 60 seconds. Preferably, the predetermined audio recording is from 3 seconds to 15 seconds, thereby allowing the user to make comments about the previous swing for later analysis. The audio recording device can also be used during the swing to record the sound of the device striking a ball for later analysis. By example, a user performs a swing immediately visualizing the path of the device across the surface based upon the light reactive surface being energized by the UV light sources passing across it, then presses the comment button, or audio recording device, to indicate details of how the swing felt and details of what was visualized on the surface. It is particularly useful for training and improvement to be able to combine the immediate feedback of the swing path visualized on the light reactive surface, with how the swing “felt” to the user, recording this information in an audio file for comparison with a 3-D visualization of the swing, either a video recording or virtual representation. The combination of the swing training device, swing analysis device, and audio recording device enables a user to analyze and reflect upon their swing performance and learn from desirable and undesirable results, thereby allowing for improvement and teaching. Alternatively, a separate video recording device can be utilized for recording the swing sequence of the user and used for later analysis. A preferred audio recording device records and stores the audio file as an electronic file for ease of transferring and playback. The audio file can be dynamically linked to the file representing a 3-D visualization of a the swing being commented upon in the audio file, thereby allowing the user to analyze the 3-D visualization (video recording or virtual representation from swing analysis device) in concert with the audio file representing the user's perception of that particular swing.
